Inter-Subarray Data Copy. The LISA-RBM (Row Buffer Movement) operation, introduced in [1]}, copies the contents of a row buffer to the row buffer of another subarray, without making use of the external memory channel.
This is achieved by linking neighboring subarrays with isolation transistors.
LISA-RBM commands are issued by the memory controller.
The total area overhead of LISA is \(0.8\%\)
